METHOD FOR IMPROVING THE RELIABILITY OF DATA TRANSMISSION OVER RAYLEIGH FADING CHANNELS

摘要

A method and apparatus for reducing the bit error probability of data transmitted over a Rayleigh fading channel are disclosed. A relatively high bit rate serial stream of data is divided into N parallel relatively low bit rate streams of data. A controlled amount of intersymbol interference is introduced in the parallel streams. The N parallel streams are then transmitted simultaneously over the Rayleigh fading channel. Each bit in the N parallel stream of data has a duration longer than the duration of the typical Rayleigh fade. Thus there is a reduced probability that a Rayleigh fade will cause a bit error.
